PNEUMA'IIC CLEANER.

To ZZ 107mm 'it may concern:

Be it known that I, Jol-IN C. TAUBER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Pneumatic Cleaners, of which the following is a specification.

This invention relates to vacuum cleaners, and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 shows a plan view of the cleaner. Fig. 2 an end elevation of the cleaner. Fig. a section on the line 3-3 in Figs. 1 and 2. Fig. 4 a section of a fragment of the top of the bellows, showing the construction of the air filter.

1 marks the bellows. These have the bottoms 2-2, the bellows leathers 3 3 and the tops The bellows are provided with the inlet valves 5 which are formed by a iiap of leather, and the outlet valves 6. These valves are kept normally closed by the springs 7.

The hinged ends S of the bottoms 2 abut cach other and are at an angle to each other, the hinged ends being higher than the outer ends 9. The bottoms in the operation of the bellows are fixed and form the compression members of the frame, the frame being completed by the tension members 10 which extend across from the end 9 of one bottom to the end 9 of the opposite bottom. This construction of frame gives it a truss shape which gives it great strength and lightness and at the same time, the raised ends S afford an opening into which the foot of the operator may be placed for holding down the cleaner while it is operated. The tops 4 are preferably in a rigid piece so that as it is oscillated, the bellows are operated alternately. Not only is this piece preferably rigid, but it is also preferably formed of a plane piece ordinarily a single board.

The dust chamber 12 in the form of a box is hinged o-n the top 4 by means of the hinges 18. It is locked in place by the catches 14. A handle 15 is secured to the dust chamber by screws 16. By oscillating the lever or handle 15, the top 4 is oscillated, and in this manner the bellows are operated alternately. The handle 15 forms a lever by means of which the box forming the dust chamber Specification of Letters Patent.

may be opened and closed. Inasmuch as it is desirable to have the joint between this box and the top tight, it is preferable to have the catches so arranged that pressure must be exerted on the box before the catch can be swung into place. The handle forms a lever for accomplishing this purpose. A hose 1T is connected with the dust chamber 12 and terminates in a nozzle 18 of ordinary vonstruction.

A preferable form of air filter and air chamber is formed by arranging a piece of metal gauze 20 over the inlets 5. This metal gauze is secured to the top 4, and as it is secured it has its edges brought together so as to arch the gauze forming a continuous chamber 19 extending from one inlet 5 to the other. Arranged over this gauze is a felt 21 forn'iing the air filter. This felt 21 is extended to form the gasket between the dust chamber and the top of the cleaner. In this manner, the dust filter and air chamber can be conveniently and cheaply constructed. By simply releasing the catches 14, the dust chamber may be opened so as to remove the accumulated dust.

By utilizing the truss form, and rigid top structure as shown with the centrally located upright oscillating handle, the operator can readily move the cleaner from place to place by lifting it with the operating handle. This lifting operation and shiftving operation can be aided by the foot of the operator which is extended into the opening between the bottoms 2 and the tension members 10. The portability of the device permits the use of a very short hose and a consequent reduction of friction and greater efficiency.

I prefer to arrange the inlet valves 5 and the outlet valves 6 directly7 in line with each other so that t-he total movement of air may be reduced as much as'possible.

That I claim as new is:

1. In a pneumatic cleaner, the combination of two bellows set end to end with the hinged ends adjacent, the bottoms of the bellows being fixed and set at an angle to each other with the adjacent ends above the outer ends, leaving a space for the insertion of a foot under the adjacent ends, the tops of the bellows being formed in a rigid piece and being in close proximity with the ends of the bottoms at the apex of the angle formed by the bottoms; a device under the bottoms adapted to be engaged by the foot of an operator; and a lever connected with said top and adapted to oscillate it as the lever is rocked.

2. In a pneumatic cleaner, the combination of two bellows set end to end with the hinged ends adjacent, the tops of the bellows being formed in a rigid piece, and the bottoms of the bellows being fixed and set at an angle to each other with the adjacent ends above the outer ends, the bottoms of said bellows forming the cou'lpression members of the frame; a tension member of the frame com'iecting the outer ends of the bottoms; and means for actuating the tops ci' the bellows.

3. In a pneumatic cleaner, the combination of two bellows set end to end with the hinged ends adjacent, the tops of the bellows being formed in a rigid piece, the bottoms of the bellows being fixed and set at an angle to each other with the adjacent ends above the out-er ends, the bottoms of said bellows forming the compression members of the frame; a tension member of the frame connecting the outer ends of the bottoms, the bellows and tension member leaving an opening permitting the insertion of a foot of the operator so as to rest upon the tension member; and means for actuating the tops of the bellows.

4. In a pneumatic cleaner, the combination of two bellows set end to end with the hinged ends adjacent, the tops of said bellows being formed in a rigid piece and adapted to oscillate to actuate the bellows; 9
